There’s been a major personnel shake-up at the National Ballet of Canada in Toronto. Artistic Associate Glen Tetley said Tuesday he will leave the company in June, and Lynn Wallis, co-artistic director, will leave the company on June 30, six months before her contract was due to expire. Tetley, who joined the company in March, 1987, plans to divide his time between New York and Italy while maintaining “a continuing choreographic collaboration with the National Ballet.” Reid Anderson will join the company as artistic director on July 1, six months earlier than planned, and Valerie Wilder, formerly co-artistic director, will become associate director.
